The existence of food cannot avoid the existence of food packaging, and the quality requirements of food packaging depend on two points: material and packaging machinery and equipment. Therefore, the identification of food packaging level in China mainly depends on the development strength of packaging and processing equipment technology< br> According to the survey and statistics of China Machinery Industry Federation, China's packaging machinery industry still maintains an annual growth of about 16%. This is because the packaging industry, as a supporting industry in many areas of the national economy, is an industry that promotes consumption and highlights value. Its technological progress and supporting services can bring profound impact on other industries< br> The fast-paced life has driven everything around us, and the packaging industry is no exception. The production efficiency of food packaging has become an important measure for enterprises, because it can reduce the cost of products and meet the delivery date. In line with the development trend of the times, packaging machinery manufacturers are paying more and more attention to the development of fast and low-cost packaging equipment, and the equipment is developing in the direction of small, flexible, multi-purpose and high efficiency< br> China's packaging machinery products are facing fierce international competition due to the lack of varieties, low technical level, poor product reliability and other reasons. Especially in the past five years, China has accelerated the development of deep processing of agricultural products, built a conservation-oriented society, developed a circular economy and strengthened technological innovation, resulting in a new round of technology introduction climax< br>
